in which situation should i say "i'm worried" and when do i say " i dont worry" , is there such thing as the latter expression though? I've been using both of them in the same context most of the time. There's definitely a mistake here but i dont know how or when do i use it correctly

" i dont worry" -> "I'm not worried"

"I'm not worried" <==> "I'm worried"

"i dont worry" means that you dont worry in general
"i'm worried" means you are worried at the time of speaking
"i'm not worried" means you are do not feel worried at the time of speaking
